Swift: Instantiate a view controller for custom transition in the current navigation stack

由 点点圈 提交于 2019-12-23 02:58:12
问题 Introduction I'm creating an app that has, in its rootViewController, a UITableView and a UIPanGestureRecognizer attached to a small UIView acting as a "handle" which enables a custom view controller transition for a UIViewController called "SlideOutViewController" to be panned from the right. Issue I have noticed two issues with my approach. But the actual custom transition works as expected. When the SlideOutViewController is created it is not attached to the navigation stack I believe,

CSS3动效(Transitions、Transforms、Animation)

理解： transition 过渡 连续的、从a到b transform 变换 旋转、缩放、偏移 animation 动画 一、transition 1.理解 　　过渡，用于平滑的改变CSS值，举个例子： change{ 　　width:100px; 　　height:100px; 　　background:yellow; 　　transition:background 10s; } change:hover{ 　　background:red; } 　　意思就是说先在change这个css样式里面“声明”：如果我的background属性发生了变化，那么它的变化过程是连续变化（渐变），这个变化过程持续10s。 　　所以，transition 就是用来定义，当一个变化发生时，它变化的连续性和时间，以及连续过程的快慢情况的（先慢后快、先快后慢等）。 　　 transition不控制变化的产生，而是只控制变化发生后的过渡效果。 2.使用 　　transition属性是下面几个属性的缩写: transition-property指定哪个属性应用过渡，比如 transition-property:background 就是指定 background 属性应用过渡。 transition-duration指定这个过渡的持续时间 transition-delay过渡延迟多长时间开始

CSS transition on png sequence using steps

由 有些话、适合烂在心里 提交于 2019-12-22 09:49:41
问题 I'm trying to make an animation using a PNG sequence, which has a transition on hover, and animates back when the hover state ends. For this I'm using a css transition with a "steps" timing function, like so: transition:background .5s steps(9, end); See the fiddle for a live example (I've used a random PNG sprite that I Googled, it's not the one I'm actually using) http://jsfiddle.net/MLWL5/ Basically this is working fine, when you hover over the element slowly. When you quickly hover on and

“Magic Move” Effect Custom Transition

由 吃可爱长大的小学妹 提交于 2019-12-22 09:14:53
问题 I trying to get a custom transition between two View Controllers. First, here's a picture to illustrate what I want : I want a UICollectionViewCell to expand to the whole screen. In this cell, the subviews are placed with Autolayout in IB. I just want each subview to go to the new position. So I tried subview.frame = newSubview.frame in the animation block, but it doesn't work (because of Autolayout I think). I thought to delete the constraints while the animation is occuring, but it doesn't

d3js transition step function

由 时光毁灭记忆、已成空白 提交于 2019-12-22 08:19:52
问题 I am using transitions in d3js and it works fine. However, is there a way to fire a function everytime the object position is updated? (for every step) Here is a some fake code: obj.transition() .ease('quad') .durantion(250) .attr('cy', function(d) { return d*d; }); I know that if you put the each(type, fn) you can get the events from end and start. But no step is available. obj.transition() .ease('quad') .duration(250) .attr('cy', function(d) { return d*d; }) .each('start', function(d) {

D3.js: run a transition continuously?

由 徘徊边缘 提交于 2019-12-22 06:56:40
问题 How can I run a transition continuously in D3.js? For example, say I want to change the body colour from red to blue and back again, continuously (I don't, that would be horrendous, but go with it). This is how I would do it once: d3.select("body").transition().duration(1000).style("background-color", "red"); How would I do it continuously? The closest examples I have seen use d3.timer , but I am not sure if there is a better way to do it. 回答1: You can use transition.each() and the "end"

REST - model state transitions

由 守給你的承諾、 提交于 2019-12-22 06:48:31
问题 In REST - revertable DELETE a nice introduction on howto model state changes in REST was given. Basically, if you have a resource with a field status , you just put a new version of that resource with an update status field. In this topic, I would like to extend this model. Say you have a resource which can be in two states: 1 and 2. In contrast with the simple model as described in the cited post, there are three transitions to traverse from state 1 to state 2, instead of just one. My

overridePendingTransition in Android SDK doesn't work

由 独自空忆成欢 提交于 2019-12-22 06:48:03
问题 I'm trying to get change the transition between two activities in an Android application. I found that overridePendingTransition would do the job, but it doesn't seem to work for me. This is the code I'm working with: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); ImageView logo = (ImageView) findViewById(R.id.ImageView01); Animation fade = AnimationUtils.loadAnimation(this, R.anim.fade_in); fade

Color transition in WPF

由 强颜欢笑 提交于 2019-12-22 06:35:36
问题 I want to make a color transition of Background color of a WPF window. How can I do this?

I don't want to be quick. Maybe an interval of 4 seconds. } 回答1: In code it can be done with this private void button1_Click

d3: Use of the *name* argument in transition.tween()

由 蓝咒 提交于 2019-12-22 05:23:58
问题 According to the documentation for transition.tween(), calling transition.tween(name, factory) ... Registers a custom tween for the specified name . When the transition starts, the specified factory function will be invoked for each selected element in the transition, being passed that element's data ( d ) and index ( i ) as arguments, with the element as the context ( this ). What is the purpose of having a named tween? Since .tween needs a reference to a transition to be used, it seems
